Red Hat Security Advisory: sudo, icecast

Apr 26, 2002, 01:30 (0 Talkback[s])

---------------------------------------------------------------------
                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Updated sudo packages are available
Advisory ID:       RHSA-2002:071-07
Issue date:        2002-04-22
Updated on:        2002-04-25
Product:           Red Hat Linux
Keywords:          sudo off-by-five heap local root
Cross references:  RHSA-2002:072
Obsoletes:         RHSA-2002:011
---------------------------------------------------------------------

1. Topic:

Updated sudo packages are available which fix a local root exploit.

2. Relevant releases/architectures:

Red Hat Linux 7.0 - alpha, i386

Red Hat Linux 7.1 - alpha, i386, ia64

Red Hat Linux 7.2 - i386, ia64

3. Problem description:

The sudo (superuser do) utility allows system administrators to give certain
users the ability to run commands as root with logging. 

Global InterSec LLC found an issue with Sudo 1.6.5p2 and earlier which can
be exploited to allow a local attacker to gain root privileges.

The Common Vulnerabilities and Exposures project (cve.mitre.org/) has
assigned the name CAN-2002-0184 to this issue.

Users of Sudo are advised to upgrade to these errata packages which are
not vulnerable to this issue.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which are
not installed but included in the list will not be updated.  Note that you
can also use wildcards (*.rpm) if your current directory only contains
the
desired RPMs.

Please note that this update is also available via Red Hat Network.  Many
people find this an easier way to apply updates.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):

These packages are GPG signed by Red Hat, Inc. for security.  Our key
is available at:

You can verify each package with the following command:
    rpm --checksig  <filename>

If you only wish to verify that each package has not been corrupted or
tampered with, examine only the md5sum with the following command:
    rpm --checksig --nogpg <filename>

                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Updated icecast packages are available
Advisory ID:       RHSA-2002:063-05
Issue date:        2002-04-11
Updated on:        2002-04-24

Keywords:          icecast buffer overflow DoS long get request
Cross references:  
Obsoletes:         RHSA-2001:004
---------------------------------------------------------------------

1. Topic:

Updated icecast packages are available which fix a number of security issues.

2. Relevant releases/architectures:

Red Hat Powertools 7.0 - alpha, i386

Red Hat Powertools 7.1 - alpha, i386

3. Problem description:

Icecast is a mp3-based broadcasting system. Buffer overflows in Icecast
1.3.11 and earlier allow remote attackers to execute arbitrary code via a
long HTTP GET request. The Common Vulnerabilities and Exposures project
(cve.mitre.org/) has assigned the name CAN-2002-0177 to this issue.

Additional buffer overflow vulnerabilities exist in previous versions of
Icecast that are also fixed by this update.  These vulnerabilities can
cause denial of service attacks as well as arbitrary code execution. The
Common Vulnerabilities and Exposures project (cve.mitre.org/) has assigned
the names CAN-2001-0784, CAN-2001-1083, CAN-2001-1229, and CAN-2001-1230 to
these issues.

Users of Icecast are advised to update to the errata packages containing
Icecast 1.3.12 which is not vulnerable to these issues.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]
